Not compatible with python 3.9

[JustDevZero]

If i try to install pykeybasebot on python3.9, even pip doesn't argue against and installs it succesfully it looks like part of the code is not yet compatible:

kbot    | Traceback (most recent call last):

kbot    |   File "/usr/local/lib/python3.9/json/__init__.py", line 359, in loads
kbot    |     return cls(**kw).decode(s)
kbot    | TypeError: __init__() got an unexpected keyword argument 'encoding'

That appears to be, because encoding keyword has been removed from python3.9:
https://docs.python.org/3/library/json.html#json.loads

This problem is already solved on new dataclasses_json versions. So, changing the version for this in pyproject.toml and also updating the rest of dependencies should do the trick.

Version with this fixed:
dataclasses-json = "^0.5.2"

That fixed it for me, thanks!
